Upload a video, click the timeline to drop split points, then export each piece. Splitting uses stream copy (no re-encoding), so it's fast — cuts snap to the nearest keyframe rather than being frame-exact.

No split points yet — the file will export as a single piece unless you add some.

Exported pieces - click play button to review, click segment name to rename prior to download.
Everything happens locally in your browser. The video file is never uploaded anywhere. This tool can handle large files. This tool only needs an internet connection the first time it runs (to fetch the video splitting engine module). It works best in a Chromium-based browser (Chrome/Edge).
Note: Split points are auto-saved in this browser and matched to the file's name, size, and modified date. If something goes wrong, refresh the page and re-select the same file; your points will be restored automatically.
